TTE940 5149 Stage 3 Turbocharger Upgrade with Oversized Inlets for BMW M3 / M4 G80 & G82 – Remanufactured Set with Heat Shield Option Included
Introducing the TTE940 Stage 3 Turbocharger Upgrade, engineered specifically for the BMW S58 engine. This package delivers unparalleled performance, combining precision engineering with race-proven durability.
Advanced Turbocharger Engineering
Each TTE940 turbocharger is meticulously remanufactured and upgraded for maximum efficiency. The original compressors are replaced with larger, high-performance billet wheels, and the compressor covers are precisely machined to achieve optimal clearances for the new compressor profiles. TTE’s 9-blade low-mass turbine wheels are installed in the turbine housings, enhancing exhaust flow, reducing gas temperatures at high boost, and ensuring rapid spool response. The upgraded bearing packs provide long-term reliability, even under extreme track conditions. TTE940 turbos are proven in competitive racing environments, including factory-level and 24-hour endurance events.
Optimized Inlet System
Included with this upgrade are TTE Oversized Turbo Inlets, designed for seamless integration with the OEM air intake system. This ensures unrestricted airflow and simplifies installation, resulting in superior boost response and maximum power potential. The combination of upgraded turbos and inlets creates the ultimate plug-and-play hybrid turbo solution.
Precision Balancing & Longevity
Turbocharger balance is critical for both performance and durability. Each TTE940 unit undergoes a meticulous balancing process:
-
Individual components are statically balanced at up to 2,800 RPM using high-precision machinery.
-
After assembly, the CHRA is dynamically balanced in multiple planes at speeds up to 250,000 RPM using our in-house VSR system.
This multi-stage process achieves an equilibrium far beyond OEM standards, improving not only performance and longevity but also acoustic quality. Every turbocharger is supplied with a serial-numbered balance test report, ensuring transparency and quality assurance.
